Specieation-formingpart of Letters Patent No. 48.917, dated July 25,1855.

- To all 'whom it may concern Be it known that I, WILLIAMy EBERHARD,

`ot' the town of Sigourneyg-in the county of 'Keokuk and State of Iowa, have invented a certain new and useful Improvement on Spinning-N Iachines; and I do hereby declare that the following is 'a l'ull, clear, and exact dscrip.

tion of the construction and operation of vthe same, reference being had to the accompanying drawings, and to the letters and marks thereon. The drawings termin g part of this specificat-ion represent a machine constructed under my invention, Figurel being atop View thereof,4

and Fig. 2 being a side View, with a portion of the top plate or platform removed, so as to showthe. gearing underneath To a frame-work, a, having a ltop plate Vor platform, b, there is connected a crank-shaft,` c, `which maybe rotated by a treadle, d, a hand.

crank, e, orv by'any suitable means driven by machine-power. Bands faroundpulleys g,at tached to the crank-shaft, operate certain movable parts of the machine, as is clearly indicated by the drawings. .'Oncband passes around the pulley h on the shortl tubular shaft t', for rottingthat'shaftan the feeding-head j thereon; another band passeslround thel pulley kfor rotating the shaft I, which, by means-of' the connecting-rod m, slide a, and fingerso, move the spool p backward and forward ;\another Vband passes around the pul-leyq for giving rotation to the spindle-head1', while-a fourthband passes around the pulley sfor rotatingr the shaft t,which, through gearing,operates the drawingrollers. Upon part or all ot' the shafts here named two or morespulleys may be placcd,'t0 provide for increasing or diminishing the speed of thc shafts, as is indicated on the main shaft and on the head of the spindles.

The feeding-head j, with its shaft and pulley,

may be made in one piece, or of 'separate pieces properly united together, and; may be of the form represented bythe drawings, or ofsa form .differing from it butretai-ning its main features. The shaft of thefeedinghead rests iusuitable 'bearings in the standards or uprights a, which are affixed to the top plate or platform, and-in which bearings the shaft rotates.

From these bearingsv the shafts may readily bc detached.

-Theheadj is somewhatfunnelshaped,its sides wideningrv ontJ from its'rentralopeningor throat,

`and there 'are affixed to its inner surface iiat springs attached to the edgeof the head b y r'rvets, and' which` taper down to the throat, thus forming the space or channel through which the roll is fed im These springs are fully injdicated by the-colored dotted lines inthe drawings. Set-screws c control ese springs, and through or by them the channel may he increased or 'diminished in order to adapt the.

Achannelto the size o't theroll used and to the material being operated upon, as themachincmay be-used for spinning wool, cotton, hemp, dax, or anyother material desired to he spun. Other means than the'springs and set-screws maybe used to vary the size of the channel. .r

There are two sets of the drawing-rollers ww' shownbutas is evident more ma be used, the diameter and sizeA 'of' these rollers, as well as their number, ,being regulated according to the size of the machine and the material used fo'r spinning or being spun.` llh'e uppery ends of theserollers have bearings in Z-shapcd bars, which are aftlxed to plates w attached to the top plate, their lower ends having bearings inthe plates x. These bearings maybe made adjustable, sc that the space between the rollers be increased or diminished, asmay be required. To the lower ends ot' these rollersare atlzred'gearing-wheels y, which may be detachable, and by which one side ot' thetwo sets o t the rollers give rotation tothe rollersotthe.

other side. The rollers-w" have aixed to theirv lower ends, below the plates w, geared wheels,

-z z', between which there is a connectingwheel,

a', attached to the plate x. That roller `of the set w which is nearest to the shaft t also has" a beveled wheel, b', gearingin with another bev! standards being suitably connected to the top plate, b. v

To the spindle-head are attached fingers f',

e een 'and aholei'n'the head of the-spindleand through. -the'head end of thek shaft, vallowe ofthe pas.

sage of the yarn or thread on its way through the endof the finger tothe spooi, as is-'t'ully .represented by Fig. 1 of the drawings.

The various and several parts of this machine maybe made ot'any of the materials usually employed in the construction of machines of this class. Many it' not all of the parts or pieces may be made by castings ot` iron orother metal; and two or more machines ean'be used arranged npon a eomm'on platform, either in connection with other machines for knitting, weaving,

ltwisting, Ste, or independently, as may he preferred.

1u using this machine, a,A piece ot' yarn or threani'ean bepassed through the head between tl1e lrzwring-rcllers, and through the hole in the head and pulley ofthe spindle and 'one ot the lfingers to the spool. y To the outer end of this thread the roll or'material to be spun in suitable condition can be attached, the mouth or entrance to the channel ot' the head and hollow-shaft being properlyproportioned by the springs andset-screu's, and the drewingeil- .ers being put in the proper condition, so that the feeding in ofthe roll end the degree of twistingthere performed end the degree of drawing exercised by the rollers shali be duly and correctly adapted to theworx to he done. Then, upon the rotation of the crank-shaft, the head is rotated, the rollersrevolved, the spindle rotated, and the spool moved backward and forward on the shaft, and the machine made to produce from theroli or other materiel the yarn or the thread in the .perfected condition.

Whatl claim as my invention, and desire to secure by Letters Patent-,.-i's- In vcombinationwith the feeding head and the d-rawingg-rollers,v the spindle and spool arranged and operated as setforth.
